To Humbolt's surprise, Schwimer has much different news. "I have just returned from the Cascades and believe I have found the missing link." There is a pause at Humbolt's end. Schwimer softly shouts, "Did you hear me, Humbolt?" When a new creature is discovered in Washington State's Cascade Mountains, adversaries Arthur Schwimer, an evolutionist, and Gary Humbolt, a creationist, join forces in a common quest to determine the scientific veracity of the latest discovery of the so-called missing link between ape and man. A sophisticated research facility is set up in the remote section of the forest where the creatures live. The substantiation of Darwin's theory- and the possible demise of the world's most established religions-rest on the results. But after the analysis begins, three members of the study group are mysteriously killed. Judith Moses, Humbolt's assistant, wades through the perplexing clues, desperately seeking answers before the seemingly indisputable research can be presented to the public. Have the researchers indeed discovered the missing link, or have they been duped by a marvel of genetic engineering?
